The 43-year-old actress and author recently opened up about her good pal Gwyneth Paltrow.

“Honestly, I look at her and I know what she does, and I know how well she takes care of herself and everybody around her,” Cameron told SiriusXM host Andy Cohen (via

). “She’s so loving and giving and generous to everybody around her, but … she was like, ‘I never blew out my hair, like, I don’t know how to do my own hair and makeup,’ and I was like, ‘Girl, after all these years, you have to know how to do this, you know?’”

Cameron continued, “So I showed her how to do a quick blowout on her own hair, and she was like, ‘That’s it?’ I was like, ‘That’s it.’ She’s like, ‘I can do that!’ I was like, ‘Of course you can! It’s easy, because we have all these other jobs that we have to do that we leave that to other people, but it’s really not that difficult to do yourself.’”
